Smaller relatives of Tyrannosaurus gave rise to some modern birds (like penguins).

There are four kinds of Tyrannosaurus eggs: blue, red, green and a special black and red color that is much larger than the others, and was the largest transformation at the Prehistoric Party 2013.

Every three minutes at the Yuck Swamp, a very large and old blueTyrannosaurus appeared. It could be possible that this was a new species, or a larger theropod such as Carcharodontosaurus or Giganotosaurus.
